Seed Grading Machine

Processing of seeds is done based on the one or more differing physical characters of seed (i.e.) seed size, length, weight, shape, surface texture, colour, affinity to liquid and electrical conductivity. In processing, first phase consists of scalping, debearding, hulling, shelling to make the seed flow readily through the grader and cleaner (conditioning and pre-cleaning).The second phase includes the removal of inert material, weed seeds, other crop and broken seeds that are larger or smaller than the crop seed.In the final (separating and upgrading) phase, undesirable materials are separated from the seed.

The machine is suitable for efficient cleaning and grading of small lots of seeds of all crops such as wheat, paddy, barley, maize, millets, sunflower, soyabean, oil seeds, forestry seeds, spices etc. Machine is very useful for research stations, breeder and foundation seed multiplication farms etc.
